Introducon

An open frame (PCB) type switching power supply is a power supply designed to be integrated or installed into a

system enclosure. Mean Well’s open frame (PCB) type power supplies include on board, general PCB, green PCB,

and medical PCB types .

Installaon

（ ）1Before commencing any installation or maintenance work, please disconnect your system from the

ulity. Ensure that it cannot be re-connected inadvertently!

（ ）2At least 5mm insulaon distance on the boom of the unit should be kept and a Mylar lm should be

added between the unit and the system. In addion, enough insulation distance, for keep10mm

general type/15mm for medical type, around the unit.

（ ）3Power supplies greater than 120W may require a forced air/fan for cooling. Please refer to

specicaons to receive a minimum air intensity and air-ow direcon.

（ ）4Allow good venlaon for the unit in use to prevent it from overheang. Also, a 10-15 cm clearance

must be kept when the adjacent device is a heat source.

（ ）5Mounng orientaons other than standard orientaon or operate under high ambient temperature

may increase the internal component temperature and will require a de-rang in output current.

Please refer to the specicaon sheets to receive the opmum mounng posion and informaon

about the -rang curve.de

Warning / Cauon !!

（ ）1Risk of electrical shock and energy hazard. All should be examined by a qualied technicianfailure .

Please do not try to x the power supply by yourself!

（ ）2Please do not install power supplies in places with high moisture or near the water.

（ ）3Please do not install power supplies in places with high ambient temperature or near re source.

Please refer to the specicaons about the maximum ambient temperature limitaons.

（ ）4Output current and output waage must not exceed the rated values on specicaons.

（ ）5The ground (FG) must be connected to earth ground.

（ ）6All MW’s PSUs are designed in accordance with EMC regulaons and the related test reports are

available by request. Since they are belong to component power supplies and will be installed inside

system enclosure, when they are integrated into a system, the EMC characteriscs of the end

system must be re-veried again.
